Title: Planar antenna
Inventor: NAKAGAWA MAKOTO
IPC: G01S3/38
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To keep the sensitivity with respect to a tilt angle of an arrived radio wave constant by conducting directivity control in a direction that power received by each antenna cell separated by a shield plate is equal to each other to decrease the wavelength dependence of the received radio wave. SOLUTION: Since a 1st cell reception wave 14 made incident in a 1st antenna cell 3 is shielded by a vertical plate 7, a dead zone 12 is formed, resulting that only a transmission radio wave in a width d2 is received. A transmission radio wave 13 made incident to a 2nd antenna cell 4 is received by the entire face of the antenna cell 4, then a 2nd cell reception wave 10 represented by a 2nd cell reception wave 10 shown in a width d1 is formed. In this case, since the reception power of the cell reception wave 10 is larger than the power of the cell reception wave 14, the planar antenna 1 is motor- controlled so as to be turned counter clockwise till the reception power of the both is equal to each other.  Since the radio wave is shielded in response to the tilt of the arrived radio wave in this way, the arrival direction of the radio wave is accurately detected without less effect of a side lobe or the like.

SOLUTION: With notches provided at a heat insulating material 15 in accordance with structures of a sleeper 11, an outer peripheral foundation and a partition, gaps appearing when the heat insulating materials 15 are arranged are reduced and at the same time, a heat insulation effect is improved for a space under Tatamis. A structure under the Tatamis 19 is such a one wherein the sides and the bottom of the sleeper 11 are covered with the heat insulating materials 15 while floor joists 13 are arranged on the heat insulating materials 15 and between the sleepers 11 and 11, and the Tatamis 19 are arranged above the sleepers 11 and the floor joists 13. Thereby, the sleepers 11 are separated by the heat insulating materials 15 from the ground surface, and transmission of cold or warmth from the ground surface to the heat insulating materials 15 is decreased. Furthermore, since the sides and the bottom of the sleeper 11 are covered with the heat insulating materials 15, the area for transmitting heat is decreased for the sleeper 11. Thereby decrease of heat insulating effect arising from thermal conduction by the sleeper 11 is restrained.

Filed: 1987-03-30
Abstract: PURPOSE:To reproduce a color picture with excellent brightness, contrast and resolution by constituting a light source by the combination of a cathode ray tube using a short after-light phosphor and a collimating lens. CONSTITUTION:A variable tuning ultraviolet light: source 1 consists of the cathode ray tube 11 having a short after image ultraviolet phospher 12 as a fluorescent screen, a barrel 13 and a collimating lens 14. The ultraviolet light obtained from the cathode ray tube 11 uses the collimating lens 14 to form nearly collimated lights 6-8. In this case, since the ultraviolet light obtained from the cathode ray tube 11 is not a point light source, accurate collimated light is not obtained and since the beam path after radiation of the collimating lens 14 is constant, no special problem is caused. Thus, a brightness modulation circuit of the light source, a conventional simple cathode ray tube drive circuit is used, and the color picture with excellent contrast, brightness and resolution is reproduced by the combination of a parabolic reflecting mirror 4 and a focus mirror 2.

Filed: 1989-03-28
Abstract: PURPOSE:To selectively perform the picture and character recording tasks by using a 1st storage means which stores the video signals and a 2nd storage means which stores the character data. CONSTITUTION:The digitized video signals, i.e., the picture data are stored in a memory circuit 2 serving as a 1st storage means. While the digitized character data D are stored in a memory circuit 3 serving as a 2nd storage means. As a result, the character data are never written into the picture data at storage and therefore some of the picture data is never changed uncorrectably. At the same time, the characters obtained from different character data can be written into a single picture by preparing many pieces of character data. Thus a video printer contains many functions.
